, This invention relates to machines'for operating upon shoes and is disclosed herein as embodied in an assembling machine.

' The purpose of the assembling machine is to perform an initial lasting operation, preparatory to the pulling-over operation. In the assembling operation anupper is placed on a last to which an insole has already been tacked in the usual manner, and a counter, which is generally molded- 10 with an inturned flange, is placed between the lining and the upper, these parts of the shoe being loosely arranged on the last as well as possible after jacking the last. The last with the shoe on it is then presented to the assembling machine, which stretches'the upper forwardly and upwardly over theheel end of the inverted last, and tacks the counter to the insole at the heel breast locality.

The flange of the counter overlaps the rear 20 end of the insole rib for a short distance, and it is necessary to turn it up and mold it into the angle between the rib and the lower face of the insole, in order that it may be sewed to the rib with the welt in the welt sewing operation, which makes it desirable to slash the flange just back of the molded portion in order that this portion of the flange may lie smoothly on the insole and be tacked thereto in the heel breast locality and that the forward portions or wings of the counter 30 may be more readily turned up against the lip.

It is also customary, in the assembling operation, to wipe down the upper over the rear end of the insole and to tack it thereto.

It has been customary in machines of this type 35 for the operator to arrange the shoe parts as well as possible on the jack in aninoperative position, somewhat removed from the operating instrumentalities of the machine, and then to move the jack into operative position in the 40 machine by hand, this movement being availed of to trip the machine and to start the operating instrumentalities forthwith. I have found that the operation can be made more positive and accurate by giving the operator an opportunity to correct the arrangement of the shoe parts after the jack has reached operative position. For example, it is vital that the upper and.

lining be properly arranged between the tensioning grippers before they close; otherwise the upper may be unevenly or unsymmetrically stretched. I

It is, therefore, a principal object of the present invention to provide a machine which will afford this advantage. Accordingly, I have provided a machine which, on being treadled, moves the jack into its operative position by power (thus relieving the, operator of the labor of moving it I himself), and then stops until it is treadled a second time, thus giving the operator ample time 6 to satisfy himself that the shoe and the operat- -VII of Fig. 11;

ing instrumentalities of the machine are in proper relationship before the actual operation on' the shoe is begun. As far as I am aware this feature of the invention is broadly novel, and its advantages are not restricted to assembling machines.

Another important feature of the invention relates-to the molding or forming of the end of the counter flange against the rear end of the insole rib. This portion of the insole rib is farther from the heel end in a large shoe than in a small one, and it is necessary, therefore, to provide for the molding operation at varying positions, relatively -vll against which the counter flange forming blow takes place comes to rest against the insole rib. This movement will be of greater extent in the case of a larger shoe than in that of a smaller one, since the insole ribs are farther apart in the former case than in the latter. Thus the operating position of the forming mechanism and of all the others is properly graded into the shoe.

Novelty is also to be recognized in the simul taneous operation of various combinations of shoe treating instrumentalities on both sides of the shoe at the heel breast region; in combinations of tensioning and slashing means and of tensioningjmeans and forming means operating at the heel breast region; in a combination of equal and oppositely moving former anvils with a jack centralizing mechanism; in a mechanism for throwingthe shoe from a downwardly and outwardly tilted position to a horizontal operative position incidental to the movement of the jack into the machine; and in a toggle mechanism for throwing the formers against the anvils. These and other features of the invention comprising certain combinations and arrangements of parts will be apparent from the following description of a preferred embodiment of the invention shown in the drawings, in which Fig. 5 is an enlarged front elevation of one side of the machine;

The machine frame is denoted by the numeral 56.

For supporting the shoe there is provided a support or jack best shown in Fig. 1. The heel end of the shoe is supported by a member i2, the.

upper surface of which is formed to engage the top of the cone of the last, and is provided with a Jack pin it. The member if is pivoted at I6 on a pin extending heightwise of the last and shoe thereon, and located forwardly of the jack pin, so that the heel end of the shoe may be centralized between two geared equiacting centralizingfingers 56 (Fig. 8) when in operative position, as will be described below. The pin I6 is mounted on a block 26 pivoted at 22 on the upper end of a jack post 26. The block 26 is provided with a pair of equalizing leaf springs 26 to effect approximate centralization of the member I2 when it is swung out of operative position toward the operator as in Fig. 1. This is effected by upstanding ears 2% on the springs 26, engaging opposite-sides of the member i2.

The axis at 22 is horizontal and crosswise of the shoe. The post 24 has an arm 30 connected by two toggle links 32, 34 to the block 20. The central point of the toggle links is carried in a slot 36 in the end of a bar 38 which is supported in a friction device 46 in the frame I6. When the jack is tipped clockwise from the position shown in Fig. 1 to operative position, the toggle joint first runs to the right end of the slot 36 and then the friction device 40 causes the toggle links to straighten and tips the block 20 about the axis 22 to bring the shoe bottom into an approximately horizontal position. The friction device then slips until the jack post 24 has been brought to an approximately vertical position.

This position of the jack is maintained by a set of differential pawls 42 which engage teeth in a plate 44 mounted at the top of a casing 46 which carries the jack post 24. The pawls 42 are pivoted in an arm 48 pivoted at" 50 on the frame Ill and are spring-pressed counterclockwise (Fig. 1) around their pivot, their movement in this direction being limited by stops 52 so that the pawls can be released from the plate 44 by pulling up on the rod 54 as will be described below.

The jack post 24 is slidably mounted in the the block 64. The compression of the spring 10 is regulated\by an abutment screw 12. The block 68 overhangs the block 64 at 14, and tends to pull it downward at times, but the block 68 can rise relatively to the block 64, the spring I0 being'then compressed. Also, a spring 16 is provided, between the portion 14 and a shoulder on the casing 46, which tends to force the block 68 downwardly. The block 68 is located in a cut-out portion at the rear of the casing 46, but does not contact with the casing; it is in effect carried slidably by the rod 66, which hangs on the bottom of the member 68, which does have a sliding fit in the casing 46.

The block 68 is pivoted at its lower end at 18 to the end of an operating lever 80, pivoted at 82 on the frame Iii. by the downward movement of the rod 84, raises the block 68 and through the spring 10 effects a resilient upward movement of the elements 64, 66 and the jack post 24. This forces a shoe on the jack up against a holddown 86 (Fig. 6) which will be discussed in more detail below.

Provision is also made for a positive non-resilient movement of the jack post, following the resilient movement just mentioned. To this end a collar 86 is slidably mounted on the bar 66. The collar 86 has (Fig. 2) two spaced ears 96 on its front side between which is pivotally mounted a clutch dog 92 on a pin 94, which is supported in the cars 66. The dog 92 is arranged to jam on a fiat place 96 on the bar 66 when turned clockwise as seen ln Fig. 2. The outer end of the dog 92 is pivotally connected to the lower end of the block 68 by a link 98. The ends of the pin 94- are embraced by notches in the ends of parallel forked horizontal arms Hill of a bell-crank lever I02 pivoted at me on the casing 46, the vertical arm of the bell-crank lever being resiliently forced clockwise (Fig. 1) by the spring 806, such movement being limited by a stop screw I08. This stop screw I68 is set so that a definite upward movement of the link 98 is necessary to turn the clutch dog 92 into gripping relation with the surface 96, and until this happensthe upward movement of the jack post is resilient: afterward, the block 68, bar 66, slide 60 and jack post 24 all move positively, together, the spring I06 yielding during the positive movement, as the pin 94 rises with the bar 66.

The jack is pulled back into operative position by a bell-crank lever IIU operated by a rod H2 and connected to the jack by a resilient link II4. This link comprises a member I I6 mounted on the casing 46 and a member II8 pivotally connected to. the upstanding arm of the bell-crank I I 0, and having a reduced front end II9 slidably extending through a guide hole in the member H6, the members I I6 and I I8 being connected by a spring I20. This movement of the jack carries the shoe under the holddown member 86, which acts to wipe down the upper and counter at the rear end of the shoe.

Those features of the invention that relate to the jack and its operating mechanism are claimed in my divisional application, Serial No. 89,196, filed July 6, 1936.

The shoe treating mechanism will next be described. This comprises mechanism for drawing therear end: of the upper of the inverted shoe tightly upward, forward and inward in the region of the heel breast line, forming the ends of the counter fianges against the insole ribs slashing the counter at the heel breast line just to the rear of the formed portions, bending the counter The rocking of the lever 80,

flange down to the insole just behind the slash, and dr ving a tack through the bent-down portion of he counter flange just at the rear of the heel breast line, on each side of the shoe. Tacks are also driven at the rear end of the heel seat and at one side of the back seam about halfway up the rear end of the counter.

At the front of the machine (Fig. 3), in its upper portion, are mounted two trunnions I22, I24, the axes of which are horizontal and at opposite angles of about 60 with the iore-and-aft direction of the machine, These have depending arms I22 I24 each of which carries a plate I26. Owing to the angular position of the trunnions these plates swing outward from each other as they swing forward around the axes of the trunnions. They are geared together by equalizing gears I26 (Fig. 6), on arms I29 (Fig. 11), so that they both move equally, when they move. They are urged toward their forward and separated position by a spring I30 (Figs. 6 and 11) which is connected to one of the gear arms I29, and are normally held against the pull of the spring I30 by a pin I32 (Fig. 6) on an arm I34. The pin I32 hooks under the end of a dog I36 (Fig. 6) springheld at I38 and attached at its lower end to one of the trunnion arms I29 by a ball joint I39.

The lower ends of the plates I26 carry the inside formers or anvils I40 (Fig. 5). As the plates I26 swing outward these anvils come into contact with the inner sides of the insole ribs I42 and support them against the blow that is delivered (Figs. 10 and 12) upon the slashed upturned edges of the counter ends, at this point, in order to mold the counter preparatory to sewing its ends into the welt seam. The swing of the plates I26 is limited by the contact of the'anvils I40 with the insole ribs, and owing to the angularlty of the trunnions, the swing, which is greater over a wide insole than over a narrow one,

will bring the anvils fartherforward on the wider insole, so that the positions of. the anvils and other instrumentalities to be described carried by the plates I26 are brought into substantially the same geometric relations to shoes of all sizes in the machine. The plates I26 also carry hamball-ended studs I60 (Figs. 5, 6, 11 and 14),

mounted on the depending arms I22, I24 of the trunnions .I 22 and I24. The bars I56 are cramped bya; slightrotation of a rod I62 journaled in the frame I0 and having a slightly projecting crosspin I63 which, when turned with the rod I62, joins the bars I58, thus locking the trunnions in operative position,

The former operating mechanism is covered by cover plates I64 parallel to the plates I26 (Fig. 3) on which are pivotally mounted two bell-crank levers I66, at I68. The lower ends of these levers have ball joint connections with pincers I10, so that throwing up these lower ends of the levers will close the pincers. The upper ends of the bell-crank levers I66 are linked by ball joints, to levers I12, pivoted at I14, on the vertical front surface I15 of the frame I0. The upper ends of the levers I12 have cam rolls working in diverging slots or pincer cams I16 on a vertically sliding plate I16 running in a guide I60 (Figs. 3 and 6), in a block I6I sliding in a vertical guide I62 in the front frame wall I16.

One pincer jaw I62 of each pair is integral with a plunger I83, the upper end of which works in a friction device I 83 (Fig. 6). The lever I66 (Fig. 3) lifts on a yoke carrying a pin I66 (Figs. 3 and 6) which works in a cam slot I66 in the other pincer Jaw I62, and also in a vertical slot in the pincer Jaw I82. The friction device I83 holds the jaw I62 from rising when the lever I66 begins to pull and consequently the Jaws close tightly before they begin to rise at all. In the reverse operation, they open before they drop, due to the action of the friction device I 63. The raising of the plate I16 by the block I6I thus first closes and then bodily lifts the pincers I10. The plate I18 is normally forced up in the guide I60 by a spring I63 which holds it against a pin I84 in the block I8I. The spring I63 yieldswhen the plate I18 meets with sufllcient resistance, permitting the block I8I to continue its upward movement. Pivots l66'of the pincer jaws I10 have backwardly-projecting, sliding, spring-supported pins I86 which ride upon cam surfaces I61 (Fig. 4) on the plates I 64, and thus resiliently.

force the pincers forward and inward as they rise to foredraw and overdraw the upper. The

. rising movement of the pincers is also resilient in plunger members I61 (Figs. 12 and 15) which slide in grooves in the downwardly-extending arms I22, I24 on the trunnions I22 and I24, behind the plates I26. The members I81 are connected at their upper ends by ball joints I66 to telescoping rods I90, I92 mounted in a head I94 having a resilient and sliding connection at I95 with a crosspiece I96 pivoted in the end of the arm I34 (Fig. 6). Each member I61 is formed at its lower end I91 to bend the counter down to the insole surface. The nozzles through which the tacks are driven are located in the ends I91 and the slashing knives 206 are fastened beside them. When the members I81 are lowered by the member I34, the resilient connection at I95 yields after the ends I91 have bent the counter flange down and positioned the tack nozzles, and after the knives 206 have slashed the counter. Each tack driver bar I96 slides in its member I61", being forced downward, when the tacks are driven, by the springs 200. When the member I34 is lifted, carrying the members I81 with it, the dogs 202 fall under abutments on the driver bars I96 and the dogs prevent the falling of the driver bars until the ends I91 and knives 206 have reached operative position. As the member I34 continues its descent, by virtue of the resilient connection I95, bars 204 trip the dogs 202, releasing the driver bars I96 which then drive the tacks 205. The trunnion arms I22 and I24 carry fingers 2I 2 (Figs. 12 and 15) which run in between the upper 2I4 and the counter 208 and lining 2I6,

and prevent tacking the upper at the breast line, the tacks going through the lining and counter flange only.

Power for operating the machine is delivered through a cam shaft 2I6 (Fig. 11) which extends through the machine and carries a number of disk-like cams keyed on it'. The first on the right,

4 z 220, has two closed cam slots 222,- 224, and a peripheral cm 226. The cam slot 222 by means of a roll 221 (Fig. 16) operates the lever -I34 pivoted on a cross-shaft 228 (Fig. 18) upon the front end of which lever I34 are hung the two tackers I81 which drive the breast tacks 206. Raising the crosspiece I86 lifts the tack drivers I81 which allows the dogs 202 to fall under the drivers, and when the member I96 drops, the springs 200 are compressed as the tack nozzles and the bars 204 trip the dogs and let the drivers operate under their spring pressure. The tacker tubes also carry the knives 206, which slas through the counter flange at 2I0.

The cam track 224 (Fig. 16) cooperates with a roll 234 on a. lever 236 (Fig. 6) pivoted on the cross-shaft 288 and having a toothed segment 240 (Figs. 6 and 11) on its front end cooperating with a rack 242 on the rear face of the block I8l (Fig. 6) which is arranged to slide in the vertical guide I82. The block I8! has a pair of hooks 244 (Fig. 6) which engage spherical knobs 246 on the levers I54 (Fig. 5) to operate the outside formers or hammers I44.

-The peripheral cam 226 (Fig. 16) cooperates with a roll 248 on one arm of a'bell-crank lever 260, pivoted at 262, the other arm of which extends downwardly (Fig. 16) and is connected to a rod 254 which runs forward and is pivoted to an arm 256 (Fig. 8) on one of the heel clamps I8. The clamps I0 are normally held in closed position by a resilient device 258, and the turning of the bell-crank lever 250 counterclockwise (Fig. 16) opens the clamp.

The next cam disk to the left of 220 (Fig. 11) is numbered 260 and has a peripheral cam 262. The disk 260 has no cams in its side faces. The peripheral cam 262 cooperates with a roll 264 (Figs. 6, 7 and 11) on a lever 266 which is pivoted at 268 on a frame arm 269 whose front end is pulled down by a spring 210 when the drop 212 is reached. The front end of the lever 266 is connected (Figs. 6 and 16) to the tack driver 214 which drives the tack 216 (Fig. 10) fed by the tube Y in the end of the heel seatof the shoe. This tack is driven by the spring 210 which is stretched by clockwise rotation (Fig. 6) of the lever 286 by the cam 262. The cam 262 also cooperates with a roll 211 (which lies behind the roll 264 in Figs. 6 and '7) on a lever 211 (Fig. 7) pivoted at 252 and having a downwardly extending arm 211 (Figs. 11 and 16) which is pulled clockwise by a strong spring 218 (Fig. 16) and is connected to the tack driver rod 280 by a ballended link at its end. The tack driver rod 280 operates in the tacker 282 which drives the tack 283 (Fig. 10) at the rear end of the shoe. This tack is driven a little to one side of the back seam, at the time the roll 211 falls off the drop 212. The tack feeding and driving mechanisms, except in so far as specifically described herein may be of ordinary construction.

The cam disk 260 has another function. It carries a pin 283 (Fig. 6) which strikes a pawl 283 and swings it to unhook the latch I36 from the pin I32, thus allowing the spring I30 to open out the plates I26 and swing the anvils I40 against the insole ribs of the shoe.

The next cam disk to the left of 260 (Fig. 11) is numbered 284 and has a cam track 286 (Fig. 7) in its left-hand face cooperating with a roll 288 on a lever 290 pivoted at 228 and connected at its front end 292 to a rod 294 which, through a crank arm 296 (Fig. 14), turns the rod I62 which looks the trunnion-carried plates I26 and the inside formers or'anvils I40. The lever 280 is pulled counterclockwise by a spring 281 when the cam 288 releases its roll 288, and the function of the rod 284, when tensioned by the cam, is to unlock the trunnions.

The next cam disk to the left (Fig. 11) on the shaft 2I8 is numbered 288 and has (Fig. 9) a peripheral cam 300 and cam tracks 302, 304 on its sides. The peripheral cam 300 cooperates with a roll 306 on an arm 308 pivoted on' the shaft 262 (see Fig. 9), which arm pivotally carries the end of the rod 84 which is connected to the rear end of the jack lifting lever (Fig. 1); The cam track 302 cooperates with a roll 3I0 on a lever 3I2 mounted on the shaft 238 and carrying the upper end of the rod 64 which unlocks the jack and permits it to fall forward into the Fig. 1 position. The cam track 304 cooperates with a roll 3I4 on one arm of a bellcrank 3I6 pivoted at 252, whose other arm 3I8 carries the upper end of the rod H2 which operates the jack drawing-in bell-crank lever H0.

The holddown 86 rises under pressure from the Jack and shoe against a spring 320 in a frame member 322 in which an upwardly extending arm 324 of the holddown 86 slides. The head 326 of the arm 324 comes up against a rigid but adjustable stop screw, 328, when the shoe has reached operative position. A proper correlation of the adjustments at 328 and I08 (Fig. 1) is therefore necessary; with the resultthat the shoe and last are rigidly held in operative position.

A clutch device 330- (Fig. 1) is provided to control the cam shaft 2I8. When the treadle rod 332 is lifted it throws a bell crank 334 clockwise. The bell crank engages a pivoted pawl 336 at 338, thus swinging a large pawl member 340, on which the pawl 336 is pivoted, clockwise and releasing the engagement with the clutch at 342..

The clutch then starts to revolve clockwise and a hump 344 strikes the end of the pawl 336 and releases the engagement at 338, permitting the member 340 to fall back and engage the clutch again at 346, stopping the machine. This initial movement of the machine brings the jack into vertical position under the holddown 86, when the operator will properly arrange the pincers and the member 2I2 before re-treadling the machine, after which the upper-drawing, slashing and tack-driving are effected.

The different cam cycles are all shown-in Fig. 17 with explanatory legends.

In operating the machine, the operator puts the last andshoe on the jack in the Fig. 1 position, and treadles the machine. After a 60' rotation of the cam shaft 2I8 the machine stops. During this rotation of the cam shaft, the jack is drawn into the vertical Fig. 6 position, the pawls 42 drop to locking position, and the latch I36 is released, permitting the inside formers I40 to swing outward and forward into contact with the inside faces of the insole ribs I42. The operator then arranges the upper and lining properly relatively to the pincers and the members 2I2 and re-treadles the machine. Between the 60 and 80 positions of rotation of the cam shaft the.

formers I40 are locked, the jack lifts and the pincers close. Between the 80 and positions the pincers rise and draw the upper forward, inward and upward. The outside formers I44 close between the 60 and positions. The heel clamps I8 close between the 100 and 110' positions. Between the and 220 positions the counter is slashed and at the 220 position the tacks 205, 216 and 283 are driven, just prior to which the pin I32 engages the latch I 36 to begin pulling back the inside formers I40 which are drawn back to initial position at the 290 position of the cam shaft. The jack then drops down (225-245) the pawls 42 rise (225-285), the pincers open and drop (2'70-310), the outside formers I are withdrawn (240-310), the tackers l8! are raised, releasing the springs 200 (240-290), the heel clamps l8 open (240- 250"), the formers I40 are withdrawn, and the jack falls forward (300-360).
